Small Vacuum Induction Melting Furnace 1kg Capacity Laboratory Vacuum Induction Melter for Alloy Research

Product Overview

This system is a compact, high-efficiency vacuum induction melting furnace designed specifically for laboratory research, academic study, and small-scale industrial alloy development. Utilizing advanced electromagnetic induction heating technology, this system enables rapid melting and precise thermal processing of metals under high vacuum, protective gas, or ambient air conditions. The furnace is engineered to handle a broad array of metals, including stainless steel, nickel-based superalloys, copper, alloy steel, nickel-cobalt alloys, and rare-earth materials such as Neodymium Iron Boron (NdFeB). By enabling the melting of small charges, this unit allows materials scientists and research engineers to conduct experimental alloy formulation and sample preparation without wasting valuable raw materials.

The primary use cases for this equipment revolve around high-temperature materials synthesis, vacuum refining of alloy steels, and precision vacuum casting. Its versatile design allows for melting and casting within the same chamber, preventing oxidation and gas absorption during the transfer of molten metal. Target industries include aerospace engineering, automotive research, semiconductor development, academic metallurgy departments, and advanced magnetics production. The integration of high-vacuum pump groups and specialized crucible systems ensures that even highly reactive metals can be processed under strict purity conditions, making this system an indispensable tool for next-generation material design.

Built with the highest engineering standards, this unit provides exceptional reliability and structural integrity under demanding operational cycles. The entire furnace body features a heavy-duty, double-walled stainless steel chamber with an integrated water-cooling jacket. This configuration ensures that while the internal temperature can exceed 2100°C, the outer shell remains cool and safe to touch. Robust mechanical linkages, high-precision vacuum seals, and an industrial-grade PLC interface guarantee consistent, repeatable results, giving operators absolute confidence in their experimental data and process safety.

Key Features

• High-Frequency Electromagnetic Induction System: Equipped with a powerful 15 kW induction power supply, the furnace delivers rapid thermal response and highly efficient energy transfer directly to the metal charge, minimizing thermal lag and ensuring fast melting cycles.
• Extreme Temperature Capability: Designed to achieve standard melting temperatures up to 1700°C, and capable of reaching elevated temperatures exceeding 2100°C when configured with an insulation sleeve and graphite crucible, allowing for the processing of refractory metals.
• Integrated Tilt-Pour Casting Assembly: Features a manual mechanical tilting device that enables smooth, controlled pouring of the molten metal directly into pre-aligned ingot molds within the sealed chamber, ensuring clean casting without breaking the vacuum.
• Atmospheric Flexibility and Vacuum Versatility: Allows melting and casting operations to run under high vacuum, protective gas atmospheres (such as Argon or Nitrogen), or standard air, providing a multi-functional platform that reduces equipment acquisition costs.
• Optional Secondary Feeding Device: Allows users to introduce secondary alloying elements, dopants, or reactive materials directly into the molten pool during the heating cycle without disrupting the chamber vacuum, facilitating complex multi-component alloy synthesis.
• Double-Walled Water-Cooled Safety Chamber: Constructed from premium stainless steel with an active water circulation jacket that maintains the exterior chamber surface temperature below 35°C, protecting operators and ensuring laboratory comfort.
• Intelligent PLC Interface and Data Management: Features an industrial touchscreen HMI that provides real-time monitoring, temperature curve programming, automated heating and cooling curves, comprehensive data logging, storage, USB downloading, and multi-level user access permissions.
